COMBINED METAL-WORKING MACHINE.

Application filed July 25, 1925. Serial No..46,172.

This is a combined metal working machine constructed and operating so as to do drillingand countersinking work, spinning rivets, and like work requiring a rotating tool spindle.

One feature of the invention is the construction set forth for both reciprocating the spindle and rotating it at the same time; and the further feature of rotatably mount- 19 ing the spindle in a cap or head on a rocker arm whereby the spindle is reciprocable,

with parts in the .upper right-hand corner thereof in central vertical section. Fig. 2 is a front elevation of the machine as shown in Fig. 1. Fig. 3 is a horizontal section of a part of the machine on the line 33 of Fig. 1, showing the spiral gearing in plan view. Fig. 4 is a vertical section of the means for supporting and elevating the spindle so that at the same time it can rotate, parts being broken away.

In the drawings there is shown a combined metal working machine with a base having thereon an upright tubular portion 11 in which there is mounted and so cured a tubular supporting standard 12. Said standard 12 is adjustably and removably secured within said tubular portion 11 by a set screw 13. The tubular standard 12 extends upward to the proper working height of the operator and on the upper port-ion thereof there is mounted asleeve 1a, as shown in F ig. 1, carrying a frame 15 having a lower arm or jaw 16 and an upper arm or jaw 17, and also carrying a frame 18 on which an electric motor 19 is mounted. Said frame on the upper part of the machine is held in position by bolts 20 extending through flanges 21 from the sleeve 14 and the upper end of the spindle.

secured to the wall of the building, not here shown.

The end of the arm or jaw 16 carries a member 22 in tubular form and vertical and parallel with the tubular standard 1.2 and adapted to hold the riveting tool 23. Any desired means may be provided on this arm or jaw 16 to carry the work that is to be treated. The upper arm or jaw 17 carries on its end a vertically disposed tubular member 25 in which the spindle 26 is mounted so as to be vertically reciprocable and said spindle is adapted to carry in its lower end a suitable tool 27 for treating the work 23. The spindlecarries a spiral gear 28that is splined thereon so that the spindle is vertically movable without such movement of the gear. Thespiral gear 28 is driven by a spiral wheel 30 on a shaft 31, and that shaft is driven by gears 32 and 83, the latter being onthe shaft 34 of the motor 19. The upper part of the arm 17 has a semi-circular recess 35 for the spiral wheel 30 and an upwardly extending portion 36 on which the worm gear 28 rests, and it has a cup shaped flange 37 on which housing 38 lies which covers the spiral wheel 28 and also the spiral gear 30, which is held in place by bolts 39 and thus the housing for the spiral wheel and spiral gear is provided.

Above the housing 38 and independently thereof there is a ball bearing race cap or housing formed of a-lower member 40 and an upper member 41 secured thereto by bolts 140. This cap or housing surrounds the ball bearing race 200, which is on the upper end of the spindle and below the wide end or head lil, which is secured to The lever is pivotally connected with the upper member 41 of said cap or housing. This construction, therefore, is such as to enable the spindle to be elevated by the lever and the cap or housing cooperating with the ball race and the nut 141 and to enable the spindle at the same time to be rotated by the gear 28.

The spindle is reciprocated by a rocker arm 45 which is fulcrumed by a pin 46 in the side members 47 of a frame which has a tra 48 on the no oer )art thereof said y .ii 1 parts it and 48 bemg integral and the side members l? are secured rigidly in place on the upper arm or jaw 17. The short and lower end of therooker arm 45 is pivoted by the links 49 to the ball bearingmember 41. The rocker arm is actuated by a connecting rod 50 that is pivoted to the long end of the rocker arm and extends down through the tubular standard 12 to the lower end of the machine, and it is elevated by a pedal lever 51 pivoted between its ends by a bolt 52 in the two posts 53 extending upwardly from the base 10. The lever 51 has a pedal 54, although it can be operated otherwise than by the foot. hen the pedal lever 51 is operated, it elevates the connecting rod 50 and the long end of the rocker arm 4-5and causes a descending movement of the spindle 26, as shown in Fig. 1. lVhen the pedal is released, a spring 55 returns the rod and the rocker armand spindle, as well as the foot lever, to their normal positions, wherein the spindle is elevated higher than as shown in Fig. 1. The elevated position of the spindle and position of the corresponding parts is'not shown; The spring is secured at one end to the rod 50 and at the other end to the sleeve 12 in such a way that the tendency of the spring is to pull the rod 50 downward and thereby elevate the spindle to its idle position. rThe actuating or operating movement of said parts is caused by the positive actuation of the foot lever.

The throw of the rocker arm and movement of the spindle 27 is limited by an adj ustable screw ,60, that is in the upper end of the frame formed by the tray 48 and the side members 47. The lower end of the screw engages the rocker arm and by turning down that screw, it will limit the actuating movement of the rocker arm and thereby the actuating movement of the tool 27 carried by the spindle 26. The tool 27 may he of such shape as to enable the machine to drill or countersink or spin rivets or merely upset rivets. The upsetting movement is primarily the result of the reciprocatory movement of the spindle 26 and tool, and this results whether the spindle rotates or not. But the drilling, countersinking and rivet spinning operations result from the combinedreciprocatory and rotary movement of the spindle. In operation the spindle is being constantly rotated and it is reciproeated asdescribed upon the application of the foot to the pedal The invention claimed is:

A combined metal working tool of the kind described, including a main frame, a gear case secured to the frame, a tool carrying a spindle mounted in said gear case, a ball bearing race cap above and independent of said gear case and in which the end of the spindle is mounted so that it may be lifted and reciprocated with said race cap and be rotatable therein at the same time, a rocker arm pivotally connected with the race cap for forcibly reciprocating the spindle, means for actuating the rocker arm, a spiral gear splined on the spindle, a spiral wheel for driving said spiral gear, adjusting means for limiting the stroke of the rocker arm, and a housing connected with said frame for said spiral gear and spiral wheel, substantially as set forth.

In witness whereof, I have hereunto ailixed my signature.

FRANK RIESS.
